I knew I would find it sooner or later. We're running a 145 main jet and a 40 pilot with the clip in the 3rd notch. It still seems just a little lean to me, so I'll probably go up to a 150 main.
Just for example, the RM used a 162 main (If I remember right) an 52 pilot and the clip was in the 2nd notch. WWWWWAAAYYYY rich for our Blaster!!

 

Okay I am going to go and try to buy a rm85 carb. Thanks. I think I will start with 150 main, 40 pilot, and 3rd notch like you did and go from there. Thanks again.[img]i/expressions/face-icon-small-wink.gif[/img]
